This study investigates charge transport mechanisms and energy level alignment in peroLED structures based on inorganic halide perovskite KPbBr₃. The device architecture ITO / KPbBr₃-PEO / Ga-In was fabricated using a low-temperature solution-based method with polymer-assisted stabilization. Current density-voltage (J-V) characteristics were analyzed to identify different conduction regimes, including ohmic conduction, injection-controlled transport, space-charge-limited current (SCLC), and trap-filled limit behavior. An energy level diagram was constructed to interpret carrier injection processes and internal electric field formation. The results demonstrate that charge transport is governed by the combined influence of energetic alignment, trap states associated with halide vacancies, and field-assisted carrier injection. The study provides insight into transport physics in inorganic perovskite light-emitting structures and highlights the importance of defect engineering for optimizing device performance.
